Answer:

P = (\frac{8}{3},\frac{11}{3})

Step-by-step explanation:

Given

X = (1,2)

Y = (6,7)

Required

The point at 1/3 of XY

If the point is at 1/3 for X, then the other end (to Y) is 2/3

So, we have:

m:n = 1/3:2/3

Multiply by 3

m:n = 1:2

The point (P) is calculated using:

P = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

This gives:

P = (\frac{1*6 + 2*1}{1+2},\frac{1*7 + 2*2}{1+2})

P = (\frac{8}{3},\frac{11}{3})

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km. Which estimate best approximates t
masha68 [24]
To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.

V = 1/3 x pi x r^2 x h
     1/3 x 3.14 x 8^2 x 1.95
V = 130.624

The approximate volume of the volcano is 131 cubic kilometers.

Answer:

Expected population in 2015: 19,152.58 or 19,000 people

Step-by-step explanation:

Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:

We can solve for the rate of decrease by using the formula:

A = a(1 - r )^{t}

where:

A = population by year 2015

a = initial population (in year 2000) = 28,000

r = rate of change (decrease by 2.5% annually or 0.025)

t = time (in number of years) = 15

Plug in these given values into the formula:

A = a(1 - r )^{t}

A = 28,000(1 - 0.025 )^{15}

A = 28,000(0.975)^{15}

A = 28,000(0.684)

A = 19,152.58 or about 19,000 people in 2015
